After showing up to Cleveland and taking his physical Friday the Cavaliers apparently have enough concern with the hip that they could reevaluate Kyrie Irving to the Celtics, at least if Thomas is included according to ESPN.

The doubt is apparently so serious that there is a possibility of the deal being voided, though no one from either team said that directly. Most trades, though, are predicated on player health otherwise teams would give away players with pre-existing injuries all they wanted to with no repercussions for not disclosing said injuries.

Thomas injured his hip last season before pulling out of the Eastern Conference Finals and sitting out the final few games. Celtics GM Danny Ainge said the injury was a signicant concern earlier this week and apparently the Cavaliers now think the same thing.

As one source involved in the process involving Thomas' medical clearance told ESPN late Friday night, "It's a very sensitive situation."

Deals have been negated by teams before due to injury with maybe the most famous one coming in MLB last year when the Padres traded an injured reliever, Colin Rea to the Marlins as part of the trade that sent Drew Pomeranz to the Red Sox.

Trades can always be voided if player health is not what they were led to believe and there is at least a possiblility that that is what will happen here.
